A systematic review of a digital twin city: A new pattern of urban governance toward smart cities

Abstract: Many countries and governments consider smart cities a solution to global warming, population growth, and resource depletion. Numerous challenges arise while creating a smart city. Digital twins, along with the Internet of Things, fifth-generation wireless systems, blockchain, collaborative computing, simulation, and artificial intelligence technologies, offer great potential in the transformation of the current urban governance paradigm toward smart cities. In this paper, the concept of a digital twin city (DTC) is proposed. The characteristics, key technologies, and application scenarios of a DTC are elaborated upon. Further, we discuss the theories, research directions, and framework regarding DTCs.

Sustainable value analysis tool for value creation

Abstract: Product-service systems (PSS) have been regarded as a promising business model to achieve sustainable production and consumption. Recent research and practice suggest the need for tools to help companies integrate sustainability into the development of PSS. The purpose of this paper is to present a sustainable value analysis tool (SVAT), and provide empirical evidence for the development and use of the tool. The tool builds on a multi-disciplinary literature analysis and qualitative data from five Chinese manufacturing companies. It is developed to assist manufacturing companies in identifying opportunities for sustainable value creation in the process of PSS development. The use of the tool in an industrial context is illustrated.

Is bitcoin a safe haven or a hedging asset? Evidence from China

Abstract: Based on daily data about Bitcoin and six other major financial assets (stocks, commodity futures (commodities), gold, foreign exchange (FX), monetary assets, and bonds) in China from 2013 to 2017, we use a VAR-GARCH-BEKK model to investigate mean and volatility spillover effects between Bitcoin and other major assets and explore whether Bitcoin can be used either as a hedging asset or a safe haven. Our empirical results show that (i) only the monetary market, i.e., the Shanghai Interbank Offered Rate (SHIIBOR) has a mean spillover effect on Bitcoin and (ii) gold, monetary, and bond markets have volatility spillover effects on Bitcoin, while Bitcoin has a volatility spillover effect only on the gold market. We further find that Bitcoin can be hedged against stocks, bonds and SHIBOR and is a safe haven when extreme price changes occur in the monetary market. Our findings provide useful information for investors and portfolio risk managers who have invested or hedged with Bitcoin.
